HAIR CURLER.

Application filed July 29,

This invention has to do with a hair curler and it is an object ot theinvention to provide a simple, eliiective and improved device of thischaracter.

It is an object of this invention to provide a simple, effective andconvenient means for holding hair in place on a hair cnrler, torinstance, on a. curling iron.

Another object of this invention is to provide an electric hair curlerWhich is sirnple, practical and inexpensive in construction.

The various objects and features of iny present invention will be bestand more fully understood fromk the following detailed description ot atypical preferred form of the invention throughout which descriptionreference is had to the accompanying drawings in it.

Fig. 1 is a side elevation of a curler, embodying the present invention.Fig. 2 is a detailed sectional View of the curler illustrated in Fig. 1.Fig. 3 is an enlarged detail sectional view of a portion of the curlerbeing a view taken as indicated by line 3 3 on Fig. 1. Fig. 4 isanenlarged detailed transverse sectional view of the curler being a viewtaken as indicated by line 1&4 on Fig. 1 and Fig. 5 is an enlargeddetailed sectional view of the curler taken as indicated b v line 5 5kon Fig. 1.

The curler or iron provided by this invention is preferably in the formof a T, having a shank portion l() and across-arm 11 at the outer end ofthe shank. This particular form of curler is useful for forming what isknown as marcel waves in thehair. A method of applying the hair to sucha curler is fully set forth in United States Letters Patent No. 1439,271issued to me December 19, 1922. The shank and crossarm of the curler areboth substantial half round in cross-sectional configuration and areformed of two sections A and B. The( section A is T shape in planconfiguration to correspond with the general shape of the curler and isin the form of a. flat plate having its edges turned to form flanges 12.The section B is shaped to conform with the section A and is curved sothat it is substantially half round in cross-sectional coniguration. Thesections A and B lit together so that the edges oi' the Section B engagethe outer edges of flanges 12 in the manner clearly illustrated in Figs.4 and 5 of the 1924. serial No. 728,852.

drawings. This construction provides a curler substantially halt roundin cross-sectional configuration, which shape is partienlarly desirableas it presents comparatively sharp corners 13 around which hair can bewrapped in a manner to give it a particularly desirable curl.

The sections A and B of the curler maybe secured together by caps 15,applied to the outer ends of the cross-arrn 11 and a handle 16 connectedwith the inner end of the shank 10. The caps 15 close the ends of thecrossarm and are eitective in preventing the hair from slipping from theends of the cross` arms. dentations 16, which (zo-operate withcorrespending indentations inthe cross-arm to hold the caps on the endsof the cross-arrn.

The handle 16 may be. formed of Wood or other suitable material and maybe of any suitable size and length. The handle tits tightly over theenlarged inner endl'porf tion 18 of the shank 10 and is secured on theshank by suitable screws 20, which extend through the handle and .intothe shank. In the preferred form of construction `a sleeve orftubularpart 19 is carried in the enlarged part 18 of the shank and the screws20 extend into the sleeve.

In accordance with ythis invention a tie 23, for instance, inthe form ofa string or tape, has one endconnected with a suitable part of thedevice and is adapted to be wrapped around or lover hair applied to theiron to hold it in place. In the preferred form of construction the tie23 has one end connected to a ring 24 freely carried on the shank 10,between the cross-arm 11, and the enlarged part 18. In use` the ring 24allows the fixed end of the tie to come at the hair carried on the iron.In practice the free or outer end of the tie may be held by theoperators hand at the handle 16 or may be otherwise suitably secured.

The means provided tor heating the curler includes a heating element orresistance Wire carried on a suitable core 31 arranged in the cross-arm11, an electrical connector 32 in connection with the handle 16 and asuitable connection between the connector 32 and the resistance wire 30.

The core 31 has a body part which extends longitudinally through thecross-arm and is provided at its ends with enlargements 34 which iitmore or less closely in The caps 15 are provided with inersy core andsection A of the curler in the man*` ner clearly illustrated in Figs. 3and 4 of the drawings. The body of the core, which is the part of thecore which carries the resistance wire, is substantially half round incross-sectional configuration to correspond to the cross-arm, and isprovided with suitable grooves or indentations 36 to carry vxthe wire30. The een ral or middle portion of the wire is carried in a groove 37extending longitudinally of the core and the two end portions of thewire are wrapped spirally around the core in the indentations 36 fromthe outer ends of the core to the middle of the core opposite the Ishank10.

rlhe electrical connector' 32 is arranged at the inner end of the handle16 in an opening 40 which extends longitudinally through the handle.rlhe particular connector illustrated in the drawings includes apair ofcontact pins 41, carried in a suitable body 42. The body 4:2 is screwthreaded into a suitable holder 44, tightly carried in the opening 40. n

The electrical connection between the resistance wire 3G in thecross-arm and electrical connector 82 atthe inner end of the handle mayinclude flexible conductors connected to the contact. pins 41, compara-Ytively heavy wires 46 which extend through the shank 10 and carry theends of the resistance wire, and suitable connections between thewires46 and the ends of the conductors 45. 1n the preferred arrangementsthe ends of the resistance wire are wrapped around the wires 46 and thewires 46 are carried in grooves 50 formed in a body 5l of insulatedmaterial rarranged in the shank 10. The grooves 50 may be closed by astrip .52of mica or other suitable insulating material. The connectionsbetween the wires 46, carrying the ends of the resistance wire, and theflexible conductors 45 are within the handle 16 and are preferablyprotected or insulated, for instance, by tubes of in sulating materialsuch as glass.

The various parts within the iron may be packed firmly in place by usinga 'suitable powder or finely divided insulating material 80.

In using the device, hair is wrapped on the curler, for instance, theshank 10, or the cross-arm 11, or both, and when necessary the tie 23 iswrapped around or over the hair and the free end of the tie is secured,for instance, by the operators hand or the handle 16. lllhen it isdesired to heat the curlerV a suitable electrical connection is madewith or through the connector 32 so that there is flow through theresistance wire 3() causing it to become heated and thereby heat thecurler.

Having described only a typical preferred form of my invention l Ydo notwish to limit myself to the details hereinbefore set forth, but wishtoreserve to myself any changes that may appear to those skilled in theart or may fall within the scope of the follow` ing claims.

Having described my invention, I claim:

1. A hair curler comprising two sections arranged together to form amain part and a projection, a cap applied to the outer ends of the mainpart of the sections to hold them together, and a handle applied to theends of the projecting parts of the sections to hold them together.

2. A hair curler comprising two sections arranged together and forming ashank and a cross-arm at the outer'part of the shank, caps applied tethe outer ends vof the crossarm, and a handle applied to the inner endvof the shank.

3. A hair curler,comprising a hair recciving portion substantially halfround in cross sectional configuration and in the form of a shank and across arm at the outer part of the shank.

4. A hair curler comprising a hair receiving portion, a tie and meanswhereby one end of the tie is slidably connected with said portion.

5. A hair curler comprising a hair receiving part having a shank and across-arm at the outer part of the shank, a ring carried on the shank,and a tie attached to thering.

In witness that I claim the foregoing l have hereunto subscribed my namethis'24 day 4of July 1924.
